## Has Microsoft set any device requirements for Windows Hello?
We've been working with the device manufacturers to help ensure a high-level of performance and protection is met by each sensor and device, based on these requirements:
- **False Accept Rate (FAR).** Represents the instance a biometric identification solution verifies an unauthorized person. This is normally represented as a ratio of number of instances in a given population size, for example 1 in 100 000. This can also be represented as a percentage of occurrence, for example, 0.001%. This measurement is heavily considered the most important with regards to the security of the biometric algorithm.

>Windows Hello face authentication does not currently support wearing a mask during enrollment or authentication. Wearing a mask to enroll is a security concern because other users wearing a similar mask may be able to unlock you device. The product group is aware of this behavior and is investigating this topic further. Please remove a mask if you are wearing one when you enroll or unlock with Windows Hello face authentication. If your working environment doesn’t allow you to remove a mask temporarily, please consider unenrolling from face authentication and only using PIN or fingerprint.

title: Windows Hello for Business Frequently Asked Questions (FAQ)
@ -137,7 +137,11 @@ sections:
- question: Can I use both a PIN and biometrics to unlock my device?
answer: |
Starting in Windows 10, version 1709, you can use multi-factor unlock to require users to provide an additional factor to unlock their device. Authentication remains two-factor, but another factor is required before Windows allows the user to reach the desktop. To learn more, see [Multifactor Unlock](feature-multifactor-unlock.md).
- question: Can I wear a mask to enroll or unlock using Windows Hello face authentication?
answer: |
Wearing a mask to enroll is a security concern because other users wearing a similar mask may be able to unlock you device. The product group is aware of this behavior and is investigating this topic further. Please remove a mask if you are wearing one when you enroll or unlock with Windows Hello face authentication. If your working environment doesn’t allow you to remove a mask temporarily, please consider unenrolling from face authentication and only using PIN or fingerprint.
- question: What's the difference between Windows Hello and Windows Hello for Business?
answer: |
Windows Hello represents the biometric framework provided in Windows 10. Windows Hello lets users use biometrics to sign in to their devices by securely storing their user name and password and releasing it for authentication when the user successfully identifies themselves using biometrics. Windows Hello for Business uses asymmetric keys protected by the device's security module that requires a user gesture (PIN or biometrics) to authenticate.

- In Active mode, Microsoft Defender Antivirus is used as the antivirus app on the machine. All configuration made with Configuration Manager, Group Policy, Intune, or other management products will apply. Files are scanned and threats remediated, and detection information are reported in your configuration tool (such as Configuration Manager or the Microsoft Defender Antivirus app on the machine itself).
- In Passive mode, Microsoft Defender Antivirus is not used as the antivirus app, and threats are not remediated by Microsoft Defender Antivirus. Files are scanned and reports are provided for threat detections that are shared with the Microsoft Defender for Endpoint service. Therefore, you might encounter alerts in the Security Center console with Microsoft Defender Antivirus as a source, even when Microsoft Defender Antivirus is in Passive mode.
- When [EDR in block mode](../microsoft-defender-atp/edr-in-block-mode.md) is turned on and Microsoft Defender Antivirus is not the primary antivirus solution, it can still detect and remediate malicious items.
- When disabled, Microsoft Defender Antivirus is not used as the antivirus app. Files are not scanned and threats are not remediated.
- When disabled, Microsoft Defender Antivirus is not used as the antivirus app. Files are not scanned and threats are not remediated. Disabling/uninstalling Microsoft Defender Antivirus is not recommended.
## Keep the following points in mind
If you are enrolled in Microsoft Defender for Endpoint and you are using a third-party antimalware product, then passive mode is enabled. [The service requires common information sharing from Microsoft Defender Antivirus service](../microsoft-defender-atp/defender-compatibility.md) in order to properly monitor your devices and network for intrusion attempts and attacks.
- If you are enrolled in Microsoft Defender for Endpoint and you are using a third-party antimalware product, then passive mode is enabled. [The service requires common information sharing from Microsoft Defender Antivirus service](../microsoft-defender-atp/defender-compatibility.md) in order to properly monitor your devices and network for intrusion attempts and attacks.
When Microsoft Defender Antivirus is automatically disabled, it can automatically re-enabled if the protection offered by a third-party antivirus product expires or otherwise stops providing real-time protection from viruses, malware, or other threats. This is to ensure antivirus protection is maintained on the endpoint. It also allows you to enable [limited periodic scanning](limited-periodic-scanning-microsoft-defender-antivirus.md), which uses the Microsoft Defender Antivirus engine to periodically check for threats in addition to your main antivirus app.
- When Microsoft Defender Antivirus is disabled automatically, it can be re-enabled automatically if the protection offered by a non-Microsoft antivirus product expires or otherwise stops providing real-time protection from viruses, malware, or other threats. Automatic re-enabling helps to ensure that antivirus protection is maintained on your devices. It also allows you to enable [limited periodic scanning](limited-periodic-scanning-microsoft-defender-antivirus.md), which uses the Microsoft Defender Antivirus engine to periodically check for threats in addition to your main antivirus app.
In passive mode, you can still [manage updates for Microsoft Defender Antivirus](manage-updates-baselines-microsoft-defender-antivirus.md); however, you can't move Microsoft Defender Antivirus into the normal active mode if your endpoints have an up-to-date third-party product providing real-time protection from malware.
- When Microsoft Defender Antivirus is in passive mode, you can still [manage updates for Microsoft Defender Antivirus](manage-updates-baselines-microsoft-defender-antivirus.md); however, you can't move Microsoft Defender Antivirus into active mode if your devices have an up-to-date, non-Microsoft antivirus product providing real-time protection from malware.
If you uninstall the other product, and choose to use Microsoft Defender Antivirus to provide protection to your endpoints, Microsoft Defender Antivirus will automatically return to its normal active mode.
If you uninstall the non-Microsoft antivirus product, and use Microsoft Defender Antivirus to provide protection to your devices, Microsoft Defender Antivirus will return to its normal active mode automatically.
